Description
technical field:
The invention belongs to the pump-unit in field of fluid machinery, be specifically related to Twisted-type rotor pump.
background technique:
The rotor pump of existing routine is made up of the rotor of static pump case and rotation, generally do not have suction valve and expulsion valve, rotor directly acts on liquid with static pressure form, and borrows the squeezing action of rotor to discharge liquid, opposite side forms low pressure simultaneously, and liquid is sucked continuously.The critical piece of rotor pump is exactly rotor, and the quality of rotor directly affects the quality of rotor pump performance.
Existing a kind of Twisted-type rotor pump, has left-handed and dextrorotation rotor, and concerning left-handed rotor, its rotor distortion several angle β, in operation process, rotor acts on axial force and drive rotor moves axially by this power.The axial force F that axial force is mainly differed from by liquid effects inlet and outlet pressure and produces
a1, i.e. F
a1=A* Δ P*B, Δ P=P

Traditional method reduces axial force by bearing, existence due to axial force can cause the damage of pump itself and prime mover (especially motor), very easily cause the axial force acted on thrust bearing excessive or too small, axial force is excessive, causes the damage of tile kilning, off-axis, seal diaphragm or increases the friction of thrust bearing, main shaft, rotor axial move the friction causing rotor and the pump housing, and prime mover load strengthens; If too small, then cause the front and back play of rotor.The defect of above-mentioned rotor design causes the major defects such as rotor pump cost is high, bearing life is low, structure is not compact.The man type rotor pump that the present invention relates to, mentality of designing is intended to the above-mentioned drawback overcoming conventional rotors pump, seeks that a kind of cost is low, axial force is little, the rotor pump of compact structure, stable movement.
technology contents:
Object of the present invention is just to overcome above-mentioned defect, designs a kind of Twisted-type rotor pump.
To achieve these goals, the present invention adopts following technological scheme:
A kind of Twisted-type rotor pump, form primarily of the pump housing, thrust bearing, power rotor and driven rotor, power rotor and driven rotor are arranged on also phase outer gearing in the pump housing, bearing is arranged on axle and pump housing joint, the side of power rotor and driven rotor and face, rotor leaf peak opposing seal, the pump housing is provided with suction port and exhaust port, have between described suction port and exhaust port power rotor and driven rotor isolated; Described power rotor and driven rotor are distortion formula rotor, and power rotor is provided with side a and b symmetric design, and driven rotor is then B end and A end, and side a and b is all distortion formula.
Rubber layer is provided with outside described rotor.
Described rubber layer is fluorine rubber.
Epitrochanterian wheel blade is no less than three.
The present invention is by a pair man type rotor synchronous backward running, the side a and b symmetric design of rotor, the axial force produced can be cancelled out each other, essentially eliminate the axial force produced in rotor pump running, the load of bearing is reduced, extend bearing working life, achieve the safe and reliable operation of rotor pump.
